Gun shop in Edmonton.
Me- Have you got any 307 Winchester brass?
Salesman- What's that?
Me- For a Winchester Model 94 lever action?
Some Customer at Counter- Oh that's obsolete no one makes that.
Salesman- I've never heard of that caliber, are you sure it's 307?
Me- (Looking at 6 boxes of factory ammo on shelve) So what are those boxes of Winchester 307 ammo for?
Salesman- Low power rounds for a 308.
That's when I left.
